At the TBTF telcon yesterday I was actioned to start discussion of how we
complete the input column of tables 5 and 6 in the MEP description in part 2
[1].
I have previously proposed text for these columns in [2,3]. Discussion in
the TBTF has been around whether we cover the error cases well enough. In
addition, the question of whether or not we should be specifying support for
overlapping requests and responses (ie. a responding node may start sending
a response prior to having fully recieved the corresponding request, and
whether a sending node should expect to start receiving a response before it
has complete the transmission of the corresponding request).
At present the single-request-response MEP specifid in part 2 does not
support overlapping request and response. It has been mentioned that
deadlocks become possible with if a responding node generate overlapping
responses, and concerns have been expressed within the TBTF about the amount
of work it would take to do a thorough job of covering the overlapping case.
In summary, we need to complete tables 5 and 6 [1]. An initial proposal is
available for discussion at [2,3] and we need some guidance on whether to
address the case of overlapping request/response.
